1. Good dimensional stability crosslinked thermoset resin matrix network structure formed body is heated role in the process, which products under normal good dimensional stability, shrinkage after molding occurs after also small. Products under long term continuous load change little in shape and size, that little creep. Creep performance depends on the load size, temperature, level and duration of the factors loading time. At a fixed load and temperature conditions, after a long load creep thermoset smaller than thermoplastics. 2. excellent heat resistance, high temperature thermosetting resin matrix composite properties after curing can not soften, heat resistance and its products fairly stable, with a load of 1.86MPa, generally heat distortion temperature in the 150 ~ 260 ℃, The fiber-reinforced thermosetting plastics belonging excellent insulating material, the thermal conductivity is generally 0.35 ~ 0.47W / (mK), only the metal of 1/100 to 1/1000, it can be used as good insulation material and moment resistance high-temperature materials, thermal deformation temperature of the material up to 350 ℃, can be used as normal and high temperature structural materials. Glass / phenolic rocket, missile engines excellent insulation material.
